Title: Kurt Nassau: Innovator in Optical Fiber Technology

Introduction

Kurt Nassau is a notable inventor based in Bernardsville, NJ (US), recognized for his contributions to optical fiber technology. He holds a total of 3 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

One of Nassau's latest patents is for an apparatus comprising Raman-active optical fiber. This invention features a Raman-active optical fiber with a very large Raman cross section. The fiber is composed of glass that includes two major components: a glass-forming first component, such as GeO2, SiO2, or AsO1.5, and a heavy metal oxide second component, like PbO or BiO1.5. The combination of these components constitutes at least 70 mol %, and preferably at least 90 mol %, of the glass. The maximum relative Raman cross section of this innovative glass is at least 15, and preferably greater than 20. This fiber can be effectively utilized in optical fiber communications systems, information processing systems with optical fiber memory loops, and optical fiber sensors.

Another significant patent addresses the issue of contact vias in semiconductor devices. In the manufacturing of integrated-circuit devices, a glass reflow step is typically employed to round off sharp edges of contact vias. However, it was discovered that unacceptable overhangs could occur on the sidewalls of the vias. Nassau's invention reveals that this overhang problem can be consistently avoided if the ratio of glass thickness to via-to-via spacing is approximately ≤0.393.
